[ssl:warn] [pid 19731] (9)Bad file descriptor: AH02026: Failed to acquire SSL session cache lock

Apache error log is showing this:

[ssl:warn] [pid 19731] (9)Bad file descriptor: AH02026: Failed to acquire SSL session cache lock

Any ideas what the above means? How to fix?

Hey there! Usually that error gets displayed in tandem with other messages in the Apache log, such as a permissions error, or a SoftException error, and that would point to the root cause of the issue. Do you see anything else in the Apache log when this problem happens that may provide more clues?
